CAP CLOSURE.

Application filed March 3, 1922. Serial No. 540,749.

This invention relates to improvements in closures for automobile gasoline tanks and the like.

The objects of the invention are to provide-an improved closure for automobile gasoline tanks, automobile radiators and the like, together with means for providing a bafiied air vent through said closure; to provide such a closurewith spring fingers for locking engagement with a part of the container, together with means for bracing said fingers and for distributing the strain at the base of the fingers; and to provide such a closure which can be manufactured at the 7 least possible ,cost and which at the same time will prove extremely eflicient in its security as a closure and in the reduction of strain and wear upon the parts.

Further objects of the invention are in part obvious and in part will appear more in detail hereinafter.

In the drawings, Fig. 1 is a plan view of my improved closure; Fig.2 is a section on line 2-2, Fig. 1; Fig. 3- is a sect1on.on line 3-3, Fig. 1; Fig. 4 is an inverted plan view of my closure;-Fig. 5 is a plan view of the tubular member to which the closure Fig. 6 is a section on line Y 9 of the closure The tubular member 1, ,which may be formed integrally with the container or sultably secured as a separate part thereto,- is

provided at its upper end with the inward- -ly extending flange portion 2 and the down- 4 wardly extending flange portions 3, the last named flange portions being separated by the recesses. 1.- The lower edges, of the flanges 3 are inclined so as to torm cam faces for engagementby the locklng member of the closurel, as. will later appear, and are provided also 'with the lugs 6 to serve as stops for limiting the rotary movement of the closure thereupon.

The closure comprises a body member having a; depending flange 7 which is adapted to engage about the tubular member 1 and is provided with the annular gasket 8 of cork or other suitable material which engages the top portion of member 1 'so as 10 seal the opening body member is provide with a central domelO, and a spring locking member with a substantially circular body portion 11 is secured tothe closure body member by crimping the base portion of the thereof. The top portion v d; the tubular mem dome 10 about the edge of the body portion 11 of the spring locking member. The crimpmg does not extend completely around said body portion, but free air passages are permitted around the base of the locking fingers 12 of the locking member so as to aiiord communication between the inside of the I closure and the chamber 13 in the dome portion 10, as will later appear. An opening 14: is provided in thetop of the dome 10 for establishing communication between chamber 13 and the outside atmosphere. The fingers 12 extend outwardly and downwardly and terminate in the angular portions 15 which are curved transversely soas to provide a substantially point contact with the.

cam edges of the downwardly extending flanges 3, as indicated in Figs. 2 and 3.

Channels or ducts 16' are provided in the closure body member in the region of connection of the base and fingerportions of the locking member, thereby providing a means of communication between the inside of the closure and the chamber 13 thereof. As. thus far described this structure is substantially the same as that disclosed in my co-pending application, Serial No. 524,396, filed December 23, 1921, to

which reference may be had for a more complete understanding of the same.

In the present. improved structure I have struck up the sheared portions 17 at the base of the locking fingers 12, thereby providing openings through the spring lockingmember at the base of the fingers '12 thereof, and at the same time utilizing the shearedportions as a baflie means for the openings to prevent the splashing of gasoline or other contentstherethrough. These sheared portions serve also as a means of'bracing the finger portions 12 at the junction of the finger'portions and the body portion 11 of the spring locking member, Therefore, the strain at the junction of the finger and base portions of the locking member is, as aresultot the present structure, so distributed that the danger of the fin er portions 12 tearing from the springloc ing member is minimized.

In order to apply the present closure to er 1 the spring. fingers 12 are inserted through the recesses 4 of said members and rotary motion is imparted to the closure so as to cause the finger end portions 15 to ride up the cam edges-until the closure has been secured to the tubular member 1 with sufliciently tight interlocking engagement. As explained in the companion application before referred. to, the gasket is relieved of the grinding action which might otherwise be caused by the rotary movement of the closure, by virtue of the yielding of the spring fingers as they ride up the cam edges of the flanges 3.

It is to be understood that in the present structure, the'vents 16 may or may not be used in-connection with the vents provided by the sheared portions 17, and it is to be understood also that dwell portions 18 may be provided in the cam edges of the flanges 3 so as to receive the finger end portions 15 and maintain them in such position.

With the present structure I am enabled to increase the air vent when employed in con junction with the original air vent 16, and at the same time protect the originalvent against the accidental escape of the gasoline or other contents. Furthermore, by bracing the spring fingers and distributing the strain at the junction of the spring fingers and the body portion 11 of the spring locking member, I am enabled to employ either bronze or brass for such spring locking member which means a decided saving in the cost of thematerial for this part of the device.

What I claim is 1. A closure, comprising a closure body, a locking member carried thereby and including a body portion and a resilient finger portion extending out of the plane of the body portion, and re-enforcing means effective at the junction of said finger portion and said body portion.

2.
